Even if you not doing anything before, the system can be broke when upgrading, so this a normal behaviour in gnu+linux some times. So if you have an uart you can see what is going on.
I started the reset process that irvinewade posted. The light was red for maybe 20-30 mins. and now went off. I’m letting it charge for awhile , will try turning it on a bit later.
I think that means: It was close to 100% charged before you started the reset process. In the 20-30 minutes, it reached full charge. The red LED goes off because it’s not charging any more (because the battery is fully charged). You should at that point take it off mains power (as a generic point about care and feeding of a Lithium battery) - even if you try turning it on only after some delay.
I don’t think that it’s a good idea to remove the battery routinely e.g. just because you are not using the phone.
I’m still fiddling with the phone , haven’t gotten it to turn on yet. Yeah I’ll leave the battery in the phone from now on. I’ll post when I get it going.
I tried all the suggestions. It will not start up. Light goes from green to yellow to red and phone vibrates about every 15 sec.The batteries are both in the high 90% of full charge because that’s what they show as when I put them into my other L5( not Byzantium) phone. Spare parts now it is.
(I wouldn’t take “putting it into another L5” as gospel. I think the other L5 can get confused by that. I would use a multimeter but let’s assume that the battery is fine i.e. working and charged.)
First check that it is not already installed. which uuu
Second, if it’s not already installed, do the install command as shown. If it’s in the Mint repo, it will install. If it’s not in the Mint repo, then it will immediately fail to install (no harm, no foul).
That means that the short answer to “Can I do this from Mint?” is “no”.
A longer answer is: Originally when I first received my Librem 5, uuu was also not in the repo for Ubuntu, so I used to git clone etc. to build uuu from sources - but subsequently uuu was made available in the Ubuntu repo.
@j8m2p6f, easiest (and safest) way might be to download and boot into PureOS Live GUI and from there: sudo apt update apt list uuu sudo apt install uuu
Now, as @joao.azevedo kindly explained, start to use Jumpdrive at the first place although just in temporary environment: lsusb | grep 8M uuu -lsusb
Jumpdrive method allows you to see and backup your files, etc. and, if needed or you decide so, ensures (prepares yourself) that the next reflash on your Librem 5 functions properly as well.
Yeah, no good. Obviously there are wider implications that I am completely ignorant of in your environment but if you were to upgrade to 21 or later then I believe your lack of uuu problem will go away.
Or you can use the Live Boot approach as suggested.
